Seriously Lordred? I had not heard that there were sometimes diminishing throughput yields related to higher NB speeds on an FX.

BRB, I will give it a try a notch lower.

Results:

It went down about .2 GB/s for me when I went with a lower NB. I have tried to get higher than 2600, but this is the highest one that is stable so far, and I have not yet tried upping the CPU/NB voltage or anything yet. This MaxxMem looks like it went way down from the 12.3 GB/s screen I posted earlier, but actually I was tinkering last night and when I tested before shutdown I had 11.9 GB/s on the MaxxMem score before I switched to a lower NB.Edited by Jagged_Steel - 7/16/12 at 9:52am

I was hoping it would be the case for me too, but it looks like 2600 is the best NB for me right now. It is awful, muggy, nasty, out today.Therefore I am going to be a chairhound and tinker some with the new FX . I was up @ 4 a.m. screwing down a deck this morning, I think screwing off the rest of the day is in order. First I am going to explore my max multi I can get with a 200 bus.

Glad I picked up a switch that mounts in a blank slot on the back . The CMOS jumper on this M5A97 became extremely tricky to reach after I added my second 6790. It could be done, but it was ship-in-a-bottle type stuff using a long stick with a slot cut in the end of it to pull that thing off and then touching the pins with a long screwdriver to clear.

On a lark I decided to try a real high bus. I set 260x16 and the FX fired right up! It is "only" running @ 4174 at those settings, but I am still impressed.

Going to go walk the multi up and see how far I can go with that high of a bus. This Samsung seems to prefer a high bus, at least it did on my 555, it was best at 244 which was the sweet spot bus speed for it. The FX hitting 260 is well, FAST !

260x19= 4.95 Ghz on the stock cooler with auto voltages This is auto memory settings. I made one attempt at setting it 8-8-8 but it failed. I managed to get 8-8-8 one multi lower @ 260x18.5. I will try and zero this thing in.

Update:Decided to pursue the 260x18.5 settings as I was able to get 1700+Mhz 8s on the Sams there. I pushed the bus up 2 at a time until it failed @ 268. 266x18.5 appears to be stable.

Still havn't seen the magic 5 Ghz yet, but I am pretty sure I can get there. I upped the auto-settings levels a bit to high/120%.Edited by Jagged_Steel - 7/16/12 at 1:12pm

i cant run my 8120 @ 4.5ghz at 1.3V and my max NB is 2400mhz. 2600 wont boot. and i increased cpu/nb voltage to 1.3V im not wanting to go water cooled, i thought my thermaltake clp0554 was gonna be good enough. but it is 82F in my house as of now.

@ 4.5GHz with only 1.3V you aren't running stable and it will fail as soon as you push all the cores to 100%
